Hamm presents new small compactors: The HC CompactLine series (EPA Tier 4/EU Stage V engines) replaces the predecessor H CompactLine series. The new compacts offer gradeability, improved driving characteristics and a comfortable, spacious cab. The 5 t (11,023 pounds) and 7 t (15,432 pounds) machines are designed to be simple to operate and offer ergonomically optimized workstations. This also makes them suited for machine rental.
The HC CompactLine series comfortably meets the requirements for compact earthwork rollers. Permanent all-wheel drive with anti-slip control and drive motors instead of a rear axle form the basis for good gradeability and high ground clearance, the company said. The developers have also further improved and stabilized the handling with various adjustments to the chassis.
Both compactors are extremely short. In particular, the HC 70i is the world's shortest compactor in this weight class, at 4.40 meters, the company said. Combined with the three-point articulation and the extremely short wheelbase, this results in good driving and handling characteristics, suited for compaction on narrow construction sites, the company said.
No specific language skills are required to operate the HC CompactLine. The logical arrangement, careful design and clear symbols on the operating elements make manual operations straightforward. The back-lit display ensures unambiguous operation, even in the dark. The arrangement of the steering wheel allows a clear view of and access to the dashboard.
In terms of visibility, the small compactors offer wide fields of vision in the open version or large window areas in the cab. A camera system with a monitor can also be added. High-quality LED work lighting is included as standard in the cab. All models in the HC CompactLine series offer convenient access to the ROPS/FOPS cab or to the open platform with ROPS, which is available with or without a protective roof and with the option of adding FOPS. The generous space offered by the completely redesigned cab with specially curved windows is unique in this market. In terms of ergonomics, the operator also benefits from the versatile adjustable seat system and a seat that can be moved to the side, wide-opening windows and draft-free ventilation. There are also plenty of storage areas, an optional USB connection and comfort options such as a tiltable steering column and an air-conditioning system.
On the small compactors, a modern engine powers the drives and power units. The compactors can operate with either diesel or HVO fuel. The sustainable machine concept includes environmentally friendly and economical operation in ECO mode. This achieves savings by limiting the engine speed. The parameters have been selected so that most jobs can be done in ECO mode, without sacrificing compaction power. In addition, the optional automatic engine stop reduces diesel consumption. It automatically switches off the engine under certain conditions, such as during prolonged downtime. At the same time, the automatic mechanism takes into account the requirements of the exhaust gas purification with a diesel particulate filter.
Thanks to their simple operation, multiple adjustments and numerous options, HC CompactLine rollers are suited for rental. For example, the rear-view mirrors can be easily adjusted and cleaned from the cab via split windows. Other options useful for rental companies include connection to the JD Link telematics system, the telematics interface for automated transfer of machine data, and the electronic battery isolation switch that protects against battery discharge and theft.
